塔里木油田凝析气井产出剖面解释方法研究
Xinan Shiyou Daxue Xuebao/Journal of Southwest Petroleum University(2013)
Abstract
近年来,塔里木盆地相继探明牙哈、吉拉克、英买力、迪那等13个高压凝析气田,在实际生产中,随着温度和压力的下降,在井筒中凝析气会反凝析出凝析油,形成油气两相,这种相态的转变使得凝析气井的产出剖面解释与普通的油气井的解释很大不同。针对牙哈、英买力凝析气藏的具体特点,采用八参数生产测井资料,在充分分析测井响应特征的基础上,利用PVT相态图和油气两相流模型两种方法分别计算凝析气井单层油气产量。实际应用表明,PVT相态图法在塔里木凝析气井的应用效果更好。
